The BioGenesis Sediment Washing Technology is a low temperature decontamination process, which uses impact forces and a proprietary blend of chemicals to remove organic and inorganic contamination from soil and sediment particles. The technology, which was patented by BioGenesis in December 2001, is designed to decontaminate both coarse-grained (sand-sized) and fine-grained (silt- and clay-sized) particles, by isolating individual particles and removing contaminants and naturally occurring organic material adsorbed to the particles. The result of the BioGenesis process is decontaminated sediment that can be used as a fill material or as a raw material in the production of topsoil or other beneficial construction grade products.
